SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 435,231, dated August26, 1890.

Application filed February 11, 1890. $erial No. 340,007. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN E. LEOKRON, a citizen of the United States,and a resident of Glenford, in the county of Perry and State of Ohio,have invented certain new and useful Improvements in Spring Bed-Bottoms;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart-to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which Figure l is a top or plan View of my improved springbed-bottom. Fig. 2 is a bottom View of the same. Fig. 3 is alongitudinal vertical sectional View on line 00 w in Figs. 1 and 2. Fig.4 is a transverse vertical sectional view on line y y in Figs. 1, 2, and3. Fig.5 is a similar view on line 5 2. Fig. 6 is a perspective detailview of the device for tightening the Wire bottom, and Fig. 7 is adetail View of a portion of the twisted supportingwire.

Like letters of reference denote corresponding parts in all the figures.

My invention has relation to woven-wire bed-bottoms; and it consists inthe combination, with the woven-wire mattress and its fixed frame, ofthe improved yielding and adjustable supports, whereby I prevent themattress from sagging, substantially as will be hereinafter more fullydescribed and claimed.

Reference being had to the accompanying drawings, the letter Adesignates the frame, which may be of any suitable size and ofrectangular shape, said frame consisting of the three parts or pieces a.The fourth side of the frame consists of a sliding piece b, the ends ofwhich are rabbeted or recessed so as to form overlapping shoulders c,which slide upon the parallel side pieces a a.

The woven-wire mattress (shown at B) is fastened at one end to the fixedend piece of the frame and at the opposite end to the movable piece'b bymeans of rods 0, which are inserted through the coils of wire formingthe mattress and securely fastened upon the end pieces a and b,respectively, by means of wire staples D.

Upon the parallel side pieces co a, forming parts of the fixed frame,are fastened, near their outer ends, the tightening devices, (see' Fig.6,) which consist of an iron bail or yoke E, recessed on its upper andunder side, as shown at e, and fastened to the side pieces of the frameby means of staples f, straddling the reduced parts of the bail, so asto effectually preventthis from slipping. I11 addition to these staplesscrews may be employed, if desired, for the purpose of holding thetightening device firmly in place. The projecting arms 6' of the bails Eare perforated near their outer ends for the insertion of the tighteningscrews or bolts F, which work through threaded holes bored in themovable end piece I). From this construction it follows that when thethreaded bolts F are turned by inserting a rod or key through thebolt-eyes F the movable end piece I) may be drawn outward upon theframe, thereby tightening the woven-wire mattress or bed-bottom betweenits fixed end and the sliding movable piece to which it is attached.This sliding piece 1) has its ends recessed or rabbeted, as shown at G,to enable it to slide upon the reduced part of the tightening devices E,which thus form a guide for said sliding piece, causing the same to movestraight forward and back without danger of its binding against thefixed sides of the frame.

In order to support the middle part of the mattress, I employ across-piece H, which has fastened to its upper side a series of helicalsprings I, the upper sides of which bear against the under side of thewoven-wire mattress. This cross-piece or middle support H rests upon asupport formed by a section of twisted wire J, consisting of a number ofspring-wires twisted together in a spiral form, as shown in Fig. 2 ofthe drawings, one end of the section being fastened permanently upon ahook K in the fixed end piece of the frame, after which it is passedover hooks L L in the sliding piece I), and then back again over similarhooks L L in the fixed end of the frame, and so on,forward and back,until its opposite end-is finally permanently fastened in the hook K inthe fixed end piece. The cross-piece H is fastened upon the twooutermost rows of wire by means of staples h it. By constructing thebottom support J in this manner-i. e., of spirally-coiled Wire it willbe seen that it is enabled to stretch when the bed is tightened byturning the threaded bolts F; and it will also be observed that thegreater the pull exerted upon this coiled wire the greater will be itstension and the firmer the support with which itwill bear against theunder side of the wire mattress through the medium of the cross-piece Hand helical springs I. In this manner I provide for a very strongsupport for the middle part of the wire mattress, which will effectuallyprevent sagging, and as the crosspiece H is fastened upon and moves withthe twisted wires J this cross-piece, with its springs, will always beapproximately under the middle part of the bed.

Having thus described my invention, I

claim and desire to secure by Letters Patent BENJAMIN E. LECKRON.
